If there is an electronic malfunction, ser­
votronic
w ill st ill function like a conven­
tional power steer ing system, prov iding a
constant steer ing support force that is no
longer proportionate to the ve hicle speed .
This is most noticeable when turning the
steer ing whee l at low speeds (for examp le
when par kin g), -more effo rt will be re­
qui red th an usual.
- Be aware of the different than usual
stee ring response and adjust you r steer­
i ng force a ccord ingly.
- Have the p roblem chec ked and set right
by an authori zed Audi dealer as soo n as
poss ib le.

Driving with your
quattro ®
With All Wheel Drive, all four wheels are driv­
en.
General inform ation
W ith All Whee l Dr ive, power is d istributed to
all four wheels. This happens automatically
depending on your dr iv ing sty le and the road
conditions at the t im e. See also ¢

E lectronic differential lock (EDL) .
Winter tires
When driving in the winter, your vehicle w it h
All Wheel Drive has an advantage, even with regular t ires. In winter road co nditions it may
be adv isable to mount winter tires (o r all-sea- son tires) for
improved driveability and brak ­
ing : these tires must be mounted o n
all four
wheel s.

Snow chains
Where tire chains a re m andatory o n certa in
roads, this no rma lly also app lies to ve hicles

Replacing wheels /tires
Vehicles wi th A ll Wheel D rive mus t always
have t ires of the same s ize. A lso avoid tires
with different tread depths . For deta ils see

page 205, New tires and replacing
tires and wheels .
Off-Road driving?
Your Aud i does not have enough g ro und clea r­
an ce to be used as an off- road vehicle. It is
therefore bes t to avoid rough tracks and un ­
even terrain as much as possib le . Also refer to
¢ page 158.
A WARNING ~
Always ad just your dr iv ing to road and traf-
f ic conditions. Do not let the extra safety
afforded by All Wheel Dr ive tempt you into
taking ext ra ris ks.
- Although the All Wheel Drive is very ef­
fective , always remember that braking
capacity is lim ited by tire t raction . You
should therefore not d rive at excessive
speeds on icy or slippe ry road s urfa ces.
- On wet road surfaces, be careful not to
drive too fast because the front whee ls
could begin to slide o n top of the wate r
(aquapla ning). If th is should occur, yo u
will have no warning from a s udden in ­
crease in eng ine speed as wit h a front­
wheel drive veh icle. Always drive at
speeds which are su ited to the road con­
d itions. -risk of crash.

210 Tir es and whe els
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains , then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13.S mm), including the lock .
Remove wheel center covers and tr im discs
before putting snow cha ins on your vehicle
¢ Q) . For safety reasons cover caps must the n
be fitted over the whee l bolts. These are avai l­
ab le from authorized Audi dea lers.
A WARNING
Using the wrong snow chains for yo ur vehi ­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
ser ious personal inj ury.
- Snow chains are ava ilable in different
sizes. Always make sure to follow the in­
struct ions provided by the snow chain
manufacturer .
- When driving w ith snow chains never
dr ive faster than the speed permitted for
your specific snow cha ins.
- Always observe local regulat ions.
([) Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wear ing the snow
chains down unnecessar ily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sa ry. Follow the i nstructions from the
snow cha in manufacture r when doing so.
(D Tips
Where snow chains are mandatory on cer­
tain roads, th is normally a lso applies to ve­
hicles with All Whee l Dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
T he design of wheel bo lts is matched to the
factory installed rims. If different rims are fit­
ted, the correct whee l bolts with the right
l ength and correctly shaped bolt heads must
be used. Th is ensures that wheels are fitted
securely and that the brake system functions correctly.
In certa in circumstances, you may not use
whee l bolts from a different vehicle -even if it
is the same model
¢page 243.
A WARNING
-Imp roperly t ightened or ma inta ined wheel
bo lts can become loose causing loss of
control, a coll is ion and serious pe rsonal in­
jury.
- Always keep t he wheel bo lts and the
threads in the wheel hubs clean so the
wheel bo lts can turn easily and be prop­
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the whee l hubs . They can
become loose while driving if g reased or
oiled, even if tightened to the specified
torque.
- Onl y use whee l bolts that belong to the
rim being installed.
- Never use different wheels bo lts on yo ur
vehicle .
- Always maintain the correct tightening
torque for the whee l bolts to reduce the
risk of a whee l loss. If the tightening tor­
que of the whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tightening torque is
too high, the wheel bolts a nd threads
